TAPE-THREADING MACHINE.

Appncanca mea July as,

To @ZZ whom t may concern.'

Be it knoWn that We, GEORGE M. FiaMEs and JOHN C. RINGE, citizens of the United States, residing, respectively, at Bridgeport.r and Stratford, in the county of Fairfield and State of Connecticut, have invented certain new and useful improvements in Tape- Threading Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

rihis inventionI relates to improvements in machines forythreading tape into articles, such as buttons and the like, and more particularly in the machine disclosed in our pending United States patent application tlerial No. 319,720, filed August 25, 1919.

rlhe invention has for an object to avoid breakage of parts of the machine and possible injury to an operator upon the presentation to the threading implements of a button or like article in which the threading apertures are distorted, or otherwise not properly spaced or correctly positioned for entrance by said implements.

Another object of this invention isto pro vide means for automatically preventing the feeding of tape to the threading implements in the event that the articleaperturespare not properly alined With the threading im'- plements for entrance by the latter.

The invention has for further object to facilitate the straightening out of jams which may possiblyy occur in the article-hopper and the chute'leading therefrom by articles clogging the passageways. Y

@ther and minor objects of the invention wil be apparent from the following descripand claims. y f ln accomplishing the objects herein set forth, the present invention has been embodied. as improvements, in the machine clearly illustrated in our pending patent application before referred to. rI'his machine comprises a plurality of reciprocating threading implements to which articles are automatically presented to be threaded With short lengths of tape. ylhe tape'is automatically drawn from a suitable supply, severed into desired lengths and presented to the threadinimplements which seize the tape 1921. serial No. 486,957.

and draw the free ends thereof through the article-apertures. The threaded articles are then automatically ejectedY from threading position. f

To threading1 implements, in the prior machine referred to, are in the form of hookneedles which enter the apertures of an article to be threaded. lf the apertures of the article are for any reason improperly positioned, it is apparent that breakage of the article or of a'machine part may occur. This not only occasions aloss by reason of Wasted time and broken parts, but'may injure an operator by flying pieces of the broken article or machine part. ln order to entirely overcome any possible defects of this character in the machine, the present invention comprehends the provision of a yielding connection between the threading implements and their actuating mechanism whereby if for any reason any obstruction is offered'to the free passage of the implements, movement of the latter is rarrested Without injury and Without discontinuing the operation of the actuating mechanism. When the threading implements are yieldingly arrested in this manner, a device is permitted to become effective to open the tape-feeding jaws to release the tape.

According to the present improvement, the article hopperl is so arranged With respeet to its driving connections as to permit of its ready removal from the machine to straighten out article-jams clogging the hop per or the chute leading therefrom.

Fig. 7 is an enlarged detail view of the threading-implement carrying bar. Fig. 8 is a plan view of the ball-re-l tainer ring sustaining the article-hopper.

Referring to the drawings, the presen-t ina-V provements are embodied in a machine supported on a base k1 and comprising a bedplate 2 from which risesthe hollow standard 3 'of theltubular overhanging bracket-arm 4 terminating in the head 5.v 1

Journaled in suitable bearings provided in the bracket-arm 4 is a rotary` actuating shaft 6 carrying at one end a belt-pulley 7 and at its opposite end aicrank 8Y connectedv by'means of a link 9 with a tubular needleactuating-*bar 10. The needle-actuating bar` 10 isjournaled for'endwise reciprocation in bushings, as 11, provided Vin the; hea-dy 5 of the machine frame. Arranged telesoopically" within the tubular bar 10 isa neede-bar 12 to the lower 'end of which is secured, by means of a screw 13, ka collar l14 having a laterally projecting armr15. suitable apertures provided in the collar 14 are the shanks 0f two threading infrp`lements` as. 16, in the V,form of hook-needles. Intermediate its'ends there is secured to the needle-.bar 12, by means of screws as` 17 a.

guide-block 18 fitted into a slideway afforded 1 by the wals o-f an elongated slot 19 provided in va tubular actuating bar 10. Threaded into the upper end of the tubular bar 10 is an adjusting screw 20, between which and the upper end of thev needle-bar `12 is interposed a coiled spring 21. The spring 21 iS fiompressedV suiiiciently by ,the adjustable screw 20 to Vnormally maintain the slidebl-ock 18 in engagement with the lower end ofthe slot 19 whereby the needle-bar 12 will f foilow the reciprocating movements of thel bar 10. 1f, however, any unusual element, such asan improperly positioned button or one in which the apertures are spaced diffe-rlently from the spacing of the threading implements, is interposed in thepath of movement of said implements, the'spring 21 will vyield to permit continued movement of the actuating` mechanism without4 causing breakage of any of thev parts., f Y As in the machine of our pri-or application hereinbefore referred to, the articles to be threaded with short sections of tape are.V

, automatically presented into threading posi- 's the article-hopper and -Chlrltf tion, but the present machine includes im! proved means fo-r supporting and lactuatimg more particular`y to Fig. 5 of the accompanying drawings, a. bracket 22 is suitably secured upon the rear side ofthe head 5 and is provided with spaced bea-ring lugs, as 23;

Rigidly secured in suitable apertures provided in the lugs` 23 isa stationary section 24 of a button-chute lformedwith a. longitudinal slot 25 for view ofthe articles passing therethrough. The lsection 24 of the button-chute extends upwardlybeyond the Secured in pulley 7 rotates the chute-section 42 and the `lil0 tionary; Further, by means ofthe described v Referringl yclosedby a two section housing 47.

A spur-gear rests V'upon the washer 29 and is suitably secured upon the Vlower end yof an article-hopper 31 within which is disposed a bushing 32 having a beveled' upper end to coincide withthe inner surfaceof the hopper. The bushing 32 is shoulderedV on its inner surfacea-djacent the beveledpor-v tion which shoulder abuts against the Vupper c end of the shuteqsection 24, thereby affording a; smooth passageway for the articles. Su'itabfry secured within the hopper 31 is: an article sieve 33 having a central aperture 34 eccentrically entered by a station-ary articleagitator 35 adjustably carried by a supporting arm 36 secured by means/of a thumbscrew 37 within a socket provided in the bracket 22. y y l y f In order to rotate the hopper 31, the spurgear 30 meshes with al similar gear 33 secured upon the upper end of a shaft 39 journaled in suit-able vbearings provided in the lugs 23. At its lower end the shaft 39 carries another spur-gear 40 in driving engagement with a spur-gear 41 rigidly secured upon the upper end of a rotary section 4 2 of the Vchuteythe section being in vertical alinement with the stationary me Y chute-section 24 and journaled inA suitable n bearings'provided'in the headk 5. Also secured upon the'chute-section 42 and below the spur-gear 41 ish-a belt-pulley 43 actuated by a belt 44, running over idlers, as 45 and embracinga belt-groove 46 provided in the driving pulleyL 7. From' thev foregoing it will'be observed that rotation of the bel*-Y hopper 31, leaving-the chute-sectionV 24 staconstruction,V the hopper 31, together with its lattachedspur-gear 30 when desired may be readily lifted off the stationary chutesection 24 V'and in fact the bracket 22,y together Vwith all the parts carriedfthereby, may be detached from the machine,both without disturbing the driving relationship of' the belt 44. This readily permits straightening out of any article-jams which may possibly occur, while theA slot inthe stationary chute-section 24 providesfor ac- A' cess to the articles particularly during the operation of the machine. The gearing for driving the article-hopper is preferably en- These housing sections rest upon the bracket 22and are secured together by means of screws as 48'.

In order to automatically transfer. the arlaoY ticles from the lower end of the rotary chute-section 42 vinto'V threading position, there vis employed substantially the. same mechanism as was'embodied in the machine of our prior patent application hereinbefore referred to and as this mechanism,V per se, does not form part of the present invention.7 onlyra general description thereof need now be repeated. n

rlhe chute-section 42, at its loweiI end which isimmediately above the bed-plate7 is formed with a longitudinal slotentered by a light spring 49 adapted to engage the lowerinost of the articles of the column thereof supported by the chute. lThe spring 49 serves to cause the article engaged thereby to rotate with the chute-'section 42 in order to properly position the article upon registering pins to be later described.

Supported for horizontal sliding movements in suitable ways provided for the purpose on the bed-plate 2 is a slide-block 50 having depending ears 51 connected by means of a link 52 with the upper end of a rock-arm 53. The rock-arm 53 projects upwardly from a sleeve 54loosely journaled between two collars as 55 upon a rock-shaft 56 supported by frame-lugs, as 57. A coilspring 58 connects the rock-arm 58 with the machine frame and acts to hold a roller 59 carried by the rock-arm against a cam- 60. rlhe cam 60 is secured upon a rotary shaft 61 suitably journaled in the machine frame and actuated by means of quartering cranks and aitmen 62 from the main-shaft 6. Adjusta ly secured upon the rearward end of the slide-block 50 by screws, as 63, so as to extend forwardly in spaced relation with respect to Vthe upper surface of theV slideblock is a longitudinallyslotted feed-slide plate 64 whose forward or article-engaging edgev is shaped to correspond substantially with the contour of the articles to be threaded. Interposed between the feed-l slide plate 64 and the upper surface Yof the slide-block 50 is a stationary longitudinallyslotted article-supporting plate 65 adj ustably' secured upon the bed-plate byl screws7 as 66. As' may be observed in Figs. 2 and 3 of they drawings. the plate 65 extends forwardly to' appoint closely' adjacent the vertical plane ef the path of movement of the two threadimplements to in part support the articles during the threading thereof. A complemental article-supporting vplate 67 extends from'the oppositeside towardthe threading implements and overliesV a spacingblock 68 secured upon the bed-plate 2 by screws, as 70, which also secure an article stripper-plate 71 provided with a transverse slot 72 to alford clearance for ,the` threading` implements. V

lt' will'be'apparent that the function of they feed-slide plate 64 is yto push into threading position the articles dropping `machine bed-plate.

from the chute upon the supporting plate 65. lt is, however, essential that the apertures of the articles be properly positioned for entrance by the threading implements. Tov this end there is provided a slide-bar 73, disposed within a clearance groove 7 4 in the slide-block 50 and beneath the supporting plate 65. The slide-bar 78 carries at its fori ward end two article-registering pins 75 projecting upwardly through the slotted articlesupporting plate 65 and feed-slide plate 64. The rearward end of the slide-bar 73 in retracted position rests upon the crossbar of a substantially U-shaped support 76 adjustablysecured by screws7 as 77, upon the. bed-plate 2. Intermediate its ends the slide-bar 73 is provided with a hook 7 9 connected by inea-ns of a coil-spring 7 9 with an upwardly extending arm 8O on the support 7 6. T he spring 79 serves to hold the slidebar 73 against the under surface of the supporting plate 65 and'tends to hold the slide in retracted position.

In the retracted position of the slide-bar 73, the pins 75 aredirectly beneath the delivery end of the chute-section 42. the lowermost article in the chute, when not registered, resting upon said pins. Rotation of the article with the chuteV by reason of the action of the spring 49 brings the apertures of the former into alineinent with the pins 75v whereupon the article drops by gravity upon the article-supporting plate The cam 60 now acts to advance the feed-slide plate 64 which engages the pinned or registered article and advances it into threading position, as illustrated in Fig. 3 of the drawings. The threading implements 16 now descendvto enter the apertures of the article and thereby depress the pins 75, which action is permitted by the clearance provided by the groove 74. The pins, when clear of the article are immediately retracted by the spring 79 into their initial position, while the feed-slide 64 is returned during the upward movement of the implements 16.

A. tape T is led from a suitable supply through an aperture provided in an ear 81 projecting laterally from a guide-flange 82 of a tension-supporting plate 83. supported for swing-out movement upon Aa stud-screw 84 and held in operative position by a registeringpin 85 and a coil-spring 86. The tape T passes freni the ear 81 past' a tensioning device 87 into a tape-guide 88 pivoted near its rearward end upon a pin 89 carried by a block 90 secured upon the A guide 91 maintains the tape-guide 88 in a vertical plane during its pivotal movements. The block 90 is provided with a transverse slot entered by a tape-guide tilting bar 92 of which the advance end is formed as an inclined fork 93 straddling the tape-guide 88', whereby longitudinal/movements of they bar v92 cause. positive swingingmovements of the tape-guide Q88 upon its pivot; g

The bar 92 is adaptedto be guided in its reciprocating movements bya slotprovided -in a block 94'suitably secured-upon the bed-4 plate.f A coiled spring 95 connected at itsV opposite ends to the block 911 and the bar 92 tends to hold the latter in retracted position, with theY delivery end of the tape-guide `depressed whereby the end of the tape is held in the path of movement of tape-.feeding means to ber-hereinafter described. The

with the block 94. From this construction` it is apparent that the position of the delivery end of the'ltape-guide is dependent upon the movement of the slide-bar 73 carrying Vthe articleregistering pins, inasmuch.. as the spring 79 is relatively stronger than the spring 95. In other words7 if no article is `dropped into register with the pins, then thefeed-slide 64 advances idly,'the registero ing pins 75 remaining stationary., which is permitted by the slotted feed-slide. When this occurs, the slide-bar 73. remains inenk gagement with the end. 97 of the two-armed 55 leverunder the action of the'spring 79,

thereby holding the' bar 92 in its advance position. Therefore if no article is advanced into threading position, the delivery end. of the tape-guide 88 remains elevated; on the contrary, every time an article is transferred from the chute to threading position. the

VVtape-guide isA depressed by reason of the movement of the slide-bar 7 3 and the actiony Y provided that isV operative underthis `ab. normal condition .to cause the jaws. to.v re-V lease the tape'4 as. the tape-feeding moveof the spring 95 upon the'bar 92. l

Referringnow more particularlyv to the tape-feeding means, a suitable slideway is provided on the bed-plate 2 for a reciproeating plate 99 transmitting actuation to the tape-feeding jaws, article-ejector andthe tape-positioning lingers. Upon the advance end ofthe plate 99 is fulcrumed kby means of a screw 100, a two-armed lever of which one arm 101 is connected by means of alongitudinally adjustable two-partv link o. 102 with a crank-disk y103. lThis connection preferably includes a slide-block 104C adjustably secured in any usual manner in a radial way105- and'pivotally connected byv means of a screw 106 with the link 102. The crank-disk 108 is carried by the upper end of a rotary'shaft-107.journaled ina bearing boss 108 of a bracket 109 suitably Vsecured upon the bed-plate 2. At its vlower end fthe shaft 107 carries a bevel-gear 110, which is actuated from a similar gear 111 carried by the shaft 6l.v The (free end ofthe .other arm,V

112 of the two-armed lever forms one meml ber of tape-grippingjaws of which rthe cooperating member isy formedfby an ear 113 upturned from .the plate 99. Secured by means. of a screw 1,14 and a steady-,pinfll upon the plate 99is a cam-member 116'havA ing an upwardly projecting pin 117 Alimiting e. vmovement of the armi' 112 in one direction.

It will ,be understood thatwhenV the plate 99 is in its eXtreme retracted position, i.e.,

toward the right in Fig. 2 of the drawings, e

and before it commences its advancingmovement toward the leftythe first action caused by the movement of the link 102 is` to swing" "the two-armedlever until the arm 112 theref of engages' the pin 1717 thereby opening the tape-gripping. jaws. Y Further oscillation .of the arm 112 beingprevented by the pin 117, the kplate* 99 is bodily advanced until the open jaws are immediately inadva'nce ofthe delivery end ofthe tape-guide A88V. The link 102 now reverses its movement, first causingv the arm 112 to swing on :its pivot thereby closing the jaws, to grip the tapethereb'etween. Y The continuedmovement ofthe link ceY 1.02 then causes the plate 99v'tobe retracted, 1

consequently drawing, the tape across the path vof the threading implements TheV path of movement of the tape-gripping aws is such that only when the delivery end of the tape-guide 88is in its lowered position will the jaws seize the tape,for the purpose previously described. i

Should it occur that the apertures in the article to be threaded are not properly alined for entrance by the threading implements, whereupon the'latter do, not complete their'q descending movementas described herein, then itis undesirable that the tape befed owing tothe waste of tape and the possibility 'of clogging ,the .operating parts of the machine. To this end nmeans is ment 'isrbegunf All' arm 118 is pivotally secured by means of: a screw 119 Vupon a bracket 120 suitably secured upon or formedV integral with the bed-plate. The free end*Y of the:y armllSy is forked to form spaced membersl 121 and 122 permitting passage` 'Y therebetween of an article ejectorVVV later Vreferred-to.V A spring 123 tends toyieldingly ment ofthe arm 15 projecting laterallylflrom normal operation of the machine, the arm 118 Vis'depressed against the actionV of its rac thelneedle-clamp collar.-,whereby, during the Y ylifting spring 123 at eachv reciprocation ofthe needle-banflf, however, the. threading l implements are arrested `in their descend` ing movement by contactfw-ithan 'article c.

ien

and 'carrying intermediate its ends an ad-v justable cam-plate 129. The cam-plate 129 is adapted to beengaged by a cam-lug 13() -provided on the cam-member 116 so that during the advancing movements of the plate 99, the fingers 128 are diverted against the action of a spring 131 out of thepath of movement of the tape-gripping jaws. After the plate 99 has been retracted suliiciently to permit the cam-lug 130 to ride the rounded end of the cam-plate 129, the spring 131 acts to cause the fingers 128 to engage the tape upon opposite sides of the ascending threading implements and hold it against the Shanks of the latter to insure seizure of the tape by the hooks of the implements. It will 'be observed that a clearance slot 132, shown in dotted lines in Fig. 2 of the drawings, is provided in the article-supporting plate 67 to permit the movement of one of the fingers 128.

Suitably secured upon the shaft 56 is a knife-carrying arm 133 carrying a camengaging element 134 actedupon by a cam i 135 provided upon the rotary shaft 61. A

coiled spring 136 surrounding the shaft 61 and one end of which engages the machine frame and the other end a collar 137 car-v ried by the shaft, holds the cam-element 134 in contact with its actuating cam. Adjustably secured upon`the knife-carrying arm133 is a knife-blade 138 of which the severing edge is movable across the path of the tape and coacts with a stationary blade 139 suitably secured upon the block 90. By means of this'construction the desiredv lengths of tape are automatically severed during the operation of the machine. v

Atapeholding finger 140 is suitably secured upon a vibratorv arm 141 projecting laterally from an oscillating shaft 143 suitably journaled in the machine frame. Secured upon the shaft 143 is an arm 144 carrying a roll 145 in engagement with a cam 146 upon the rotary shaft 61. The roll 145 is held in engagement with its actuating cam by means of a coil-spring 147 surrounding the shaft 143 and one end of which enters an aperture in a collar 148 adjustably secured upon the latter shaft while the other end bears against a portion of the machine frame. The function of the finger 140 is to engage the tape between the apertures of the article and hold the tape against bodily movement during the threading operation, thereby insuring that the free ends of the threaded tape are of substantially equal lengths.

As in our prior patent application hereinbefore yreferred to, there is provided an article-ejector 149, a guard 150 and a chute 151 but, as these parts form no direct part of the present invention7 nol further description thereof is deemed necessary.y
